com.mbeddr.mpsutil.refactoring not available in JetBrains plugin repository

[eugenschindler]

I can't find the com.mbeddr.mpsutil.refactoring language (needed for me mainly for the ProjectionModeSwitcher) in the JetBrains plugin repository. It could be made available, but it may also be considered to factor out the ProjectionModeSwitcher into a separate util (since from the outside it doesn't look like it logically belongs to "refactoring" utils) and then publish it on the JetBrains repository.
