This, pretty much.

Some projects use various build system hacks/workarounds in order to
"spare" the make install stage.
Personally not a huge fan of those, regardless - if project A opts for
it, they must ensure that things just work.

Adding workaround(s) in users does not scale and is a bad idea overall.
