I ride 32mm tubeless GP5000 on hardpacked dry dirt and "light" gravel trails (think crushed limestone) all the time. It's great.
I've never found much advantage to file treads. I've tried them for early season dry CX racing and always found the cornering traction to be weird, and the filed down center doesn't really seem like it rolls any faster than a normal tread. I do like tires like Challenge Baby Limus, which is a slightly filed down version of the regular Limus, but something like a Chicane? I don't get it.
