It's not diverging the name other than splitting the files from a single
upstream into two packages. upstream installs both xkeyboard-config.pc
and xkeyboard-config-2.pc.

Long-term upstream expects the format to change but for backwards-compat
reason we'll never be able to change the current version that's been in
use for decades. So any current software will require
xkeyboard-config.pc but can (at this point) be safely switched to
xkeyboard-config-2.pc and get the same file (but in different paths).

But at some point in the future xkeyboard-config.pc (and files) will be
decoupled properly and frozen so it's standalone while the versioned
approaches continue at their own pace.

Anyway, that's the upstream plan, right now the TLDR is:
xkeyboard-config upstream installs both .pc files so this is merely 
prep work so that in 10 years time we can install
xkeyboard-config-legacy and xkeyboard-config-5, depending on which local
applications we have that require XKB layouts.

Cheeers,
