Think of the little ones.
I often work with severely constrained platforms - mostly 32-bit Arm these days but nonetheless with available RAM in the hundreds of kilobytes not megabytes and hundred megahertz not gigahertz CPUs. Stacks like lwIP/mbedTLS can handle this with HTTP on top. I'm not sure I'd like to try adding QUIC. So now the server end will have to implement two parallel interfaces for the first and second class clients. I can understand Apache's hesitation.
