If they're accurately labeled, I'd say use 'em, but I somehow got the idea
those are used in writing proofs to express logical entailment (or whatever
the term is) or something like that, rather than truth.  I.e., I suspect
Unicode got the labels slightly wrong.  But I must also stress that I'm not
a logician, I only play one on the internet.  I'm quite fond of
non-sequiters, especially since my tennis shoes are in the wash.  I guess my
main objection to U+22A8 and U+22AD is they seem to define false in terms of
true, which seems to denigrate falseness, and is clearly insensitive to
