Modern Tourney vs unused decade-old Deore derailleurs?
Do the group set standards evolve in line with technology development so that they eventually surpass their superior counterparts from the past?
Or does Shimano keep the technology tiers consistent by design?
Can a 2020 Tourney derailleur shift as well or better than 2005~2010 Deore derailleur for example?

I'd rather have a 15 year old Deore (assuming the condition was OK).

My old XT derailleur from the early to mid 90s is still going strong and shifts like a dream I hope it never dies which so far has held up for at least 24 years. Tourney is crap no matter what era. I would probably rather have the Deore as that might have been 9 speed or maybe even 10 speed which is a lot more quality than 6 or 7 in 2021 (which first came out in the 80s and was largely replaced in the 90s with 8 and 9 speed)

I am considering whether to buy and mod a new entry level bike with a tourney on it or not. I was testing it and I wasn't able to feel the difference among it and altus/acera/alivio on my old bikes. It's been a while since I rode a bike with deore, mine's sitting in the parts bin right now.

My 2018 Giant Sedona comfort bike came with a 7 speed Tourney rear derailleur. I didn't have any problems with it until clumsy me stepped on it. It was replaced with a Altus Derailleur. This too is a low end unit but seems much more substantial.
I wouldn't expect it to be as good as older higher end derailleurs though. With just 7 speeds it probably isn't rocket science to design and build an inexpensive rear derailleur that is both durable and shifts well. At least not for Shimano. These guys have a knack for building low priced components that do exactly what's advertised. Perhaps that's one reason they are so popular with bike manufacturers.
For the recreational bike riding I do, I didn't consider high end components to be important. Given a choice I would probably choose higher performance parts, But the bike I wanted, For its bolt upright seating, 26" tires, Rim brakes, and 2" wide smooth riding tires came with a more basic level of components. Surprisingly the 3 x 7 speed Altus transmission works WAY better then it has any right to, And the cheap Tektro rim brakes stop me in the rain. No reason to upgrade!

Why would you buy that level bike to “mod out” . Seems like throwing good money after bad. This is not like the old days where you would buy your mongoose California and replace every single part on it within six months

I agree. No reason to buy that stuff if you have a choice.

Mostly because I already have the parts and I just need to put them on. Vitus Dee is pretty much what I am looking for even though the specs don't stand out.

"Technology" may trickle down, but not entirely. The tucked-in Shadow parallelogram has been moving down-market. Deore is still the lowest level with a clutch and all the clutch models are 10+ speeds.
Quality does not trickle down. The levels are sliced pretty thin but...
XT will get you mostly ano aluminum forgings, any steel parts plated or stainless
Deore will get you a mostly-metal assembly with powder coat or some other really tough paint on the some of the steel, some parts stainless, and a few aluminum forgings
Tourney is all galvanized stamped steel and injection molded plastic
