Well, yes. Vimscript plugins will see better adoption. Lua matters for compute-heavy plugins.

Language design is not the full picture. init.lua is essentially a thinly-veiled init.vim with lua syntax. You will have to learn init.vim either way. It is extra work to do something in init.lua, and in using it you remove any chances of it ever working with an installation of vim (e.g. vim still has the best GUI options out there).
