I think if a user, who runs PostgreSQL on a multicore machine with high-concurrent load, can take care about installing the appropriate package/using the appropriate compiler (especially if we publish explicit instructions for that). In the same way such advanced users tune Linux kernel etc.
BTW, how do you get that required gcc version is 9.4? I've managed to use LSE with gcc 9.3.
