Indeed none of meson, cmake and debhelper are build-essential. I think
we've vaguely tried that with cross-config, which happens to still be
pulled by sbuild, but not by pbuilder. I recommend not repeating this.
For another thing, keep in mind that Debian is not the only user of such
functionality. My original approach to this was adding debcrossgen to
meson, but Jussi Pakkanen argued in favour of including it in meson
proper and now it is "meson env2mfile" - a core meson functionality.
Users (or CI) building stuff on Debian systems but without a Debian
package is thus enabled to use Debian's cross build infrastructure in an
easy way: meson env2mfile knows how Debian works and will produce a
suitable crossfile.

While I appreciate "there is more than one way to do it", there also is
value in "There should be one-- and preferably only one --obvious way to
do it." An ind this case, my impression is that the world is converging
towards the other way (from Debian point of view). The question kinda is
how accurate that impression is.
Hence, I think that if we're going to change the way we pass cross flags
to cmake, we should do it like meson does by providing a tool inside the
cmake package.
