Request #4670 has been rejected by arcanis [1]:
Service file has been modified 2015-11-29. Package has been updated
2016-01-30 (optdep has been dropped). So for now I'm closing this
request.

Request #4651 has been rejected by arcanis [1]:
I see no reason to remove this package. Moreover the PKGBUILD is just
implementation of official (or semi-official) Steam documentation.
