Meson is still marked as experimental right now, so I don't think this
needs to be explicitly called out. We should start to be more mindful of
any backwards-incompatible changes once Meson support has matured a bit,
say for example starting with Git v2.49 or v2.50. But until then it's
kind of expected that we'll still have to iterate a bit.
