I'd say the drivetrain fad definitely has shifted to larger and larger cassettes, rather than chainrings below 24t.
I think the deore xt talked above in this thread is a great option. I've got it on my 90s MTB and it has the classic 42/32/22, or whatever, I can't remember exactly. Nice quality, shiny silver, not a boat anchor, and there are plenty of square taper cartridge bottom brackets still available.
Personally I agree with others, wayyy easier to go for 74BCD and change around the rear cogs to get the gearing you want, the look you want, and the low weight you want.

Each time I see this thread bumped up it makes me wonder... Just out of curiosity... Have you actually rolled with 20 or 22 (or 24) tooth chainrings?
I'm full-on in favor of low gearing. But I also seem to recall a quote from Sheldon Brown- "sometimes it's just better to walk." For me- if I hit a hill with, say, 30 pounds- by the time I'm down to the 28 I'm going slow enough that it's more work to stay upright than it is to

The advantage of an 18-inch low gear is that you can climb 16 to 20 percent slopes with a load (as I’ve done) and keep going when the grade eases off. It’s a lot easier to shift up a gear or two than jump back on the bike after walking.

Davinci cranks qualify as they have changeable spiders, including the option for a 110/58. I'm not sure how you order from them other than by direct contact

mid-compact and compact road cranksets exist largely due to the availability of small cogs - first 11t then 10t and now more recently even 9t
1x drivetrains are now standard equipment on just about every mid to upper level off road bike (similar to pictured above) - most 1x drivetrains include a downsized chainring - and in addition to the large cogs for climbing, small cogs are featured for top end

the large cassettes featuring the large cogs for climbing most often also include a small cog for top end (9 - 11t) - and feature downsized chainrings
example above - 40t chainring with 10-42 cassette

Yes, but chainrings below 24t (heck, more like 30t) have been vacated nearly entirely in favor of large cassettes, like I said.

30t (etc) chainring is common - no big rings like a 42, 44, etc … and these drivetrains largely made possible by the small cogs on those large cassettes … for the Stumpjumper in the prev picture 30t ring and 10-52 cassette
