Do you mean the first sentence or the second sentence?

I agree the first sentence is demotivating but I feel the same spending a lot
of time rebasing patches again and again on changes that end up half-way or
that are questionable whether they really cleaned up the code.  Although
specifically for this TRY_CATCH->TRY case I had fortunately only two such
cases.

For the second sentence I hope everybody - and at least Google - agrees, that
G++ is not usable for C++ development as in many cases particularly involving
templates the error messages only say something is wrong in the source,
without giving the invalid source line number.  I was bisecting the source
before I found clang++ can just report the invalid code location.  I have
filed many diagnostics PRs for GCC but almost none of them are fixed yet.
G++ is great to get a bit better performing final code after all the
compilation errors are resolved by clang++.
