You are exagerating and that does not help communication.  In this
group there were at least one serious poster claiming to write code
depending only on features from older C standard.  People like this
presumably would care if some "toy" compiler discoverd non-compliance.
Concerning tcc, they have explicit endorsment from gawk developer:
he likes compile speed and says that gawk compiles fine using tcc.

In may coding I use gcc extentions when I feel that there is
substantial gain.  But for significant part of my code I prefer
to portablility, and that may include avoiding features not
supported by lesser compilers.  I the past tcc was not able
to compile code which I consider rather ordinary C, and due
to this and lack of support for my main target I did not use
tcc.  But tcc improved, ATM I do not know if it is good enough
for me, but it passed initial tests, so I have no reason to
disregard it.

BTW: IME "exotic" tools and targets help with finding bugs.
So even if you do not normally need to compile with some
compiler it makes sense to check if it works.
