Description of this change

[ujohnny]

we agreed with @tpasternak to shelve it for a while as with other sdkcompat layers it will make clwb project view file hard to read as wildcards are not supported in project view.

Not exactly because I prefer having long ignorelist in projectview :D than seeing red squiggles in tree panel, but it's not that important to me so I can give up :D
