The question is more of a compatibility one than anything else. What, if anything breaks if you do this?
As noted, there are contexts in which not computing the checksum works. So I guess the conclusion is that nothing breaks, so go ahead. QUIC doesn't depend on the checksum. All the cryptographic bits of QUIC use far stronger and more reliable mechanisms.
