Well, that sort of thing works great as a local solution, but consider
reused scripts,
tools, etc. recipes, if you take one of those and run it in your
environment, will it do the
right thing, the expected thing? Will it do the expected thing if you
have both qt 5 and
qt 6 on your system? Will it do the expected thing if you have just
one of them? Will
it do the expected thing if you have just one, and then switch to the other?

Therein lies the reason for the fuzz and fuss about the correct global name.
