We disabled bash completion support for .NET Core 2.2 (rh-dotnet22-dotnet) because the bash-completion files conflicted with the ones from .NET Core 2.0 and 2.1. We should look into re-enabling them.
A simple fix is to take the latest version of the upstream bash completion file (it is backwards compatible with 2.x) and include that latest version in all our packages.
