Difficult to say, indeed.
I know this much, though. CMake seems to have this philosophy where=20
build rules do different things depending on your version of cmake, and=20
depending on which version that is, you *might* be able to specify=20
https://cmake.org/cmake/help/v3.0/manual/cmake-policies.7.html to go=20
with the old or new behavior.
meson prefers to deprecate things that were decided "this is bad", and=20
issue warnings maybe forever (I think it's been considered to drop=20
deprecated, warning-raising functions for the 1.0 milestone? not=20
guaranteed), then reimplement the better functionality as a new function =
or function keyword argument. The idea is specifically to avoid changing =
how old build files get processed. Instead, if developers want their=20
builds to configure without big yellow warnings, they need to migrate to =
"the newer way".
Obviously this doesn't guarantee meson is always *successful* in being=20
backwards-compatible. :)
