JTS 6.0.3: new restriction (invalid characters & " ' /) for Team Area names?

The current milestone of JTS 6.0.3 comes with a new limitation on the characters allowed in the Team Area name field.

I'm getting this error when creating or modifying a Team Area:

The area cannot be created because its name includes one or more of these invalid characters: & < > " ' /ID CRJAZ6043E

Except the forward slash, the rest were valid characters in previous versions.

To reproduce the problem, simply attempt to modify the following Team Area from one of the Jazz.net sandboxes (just remove an s at the end of the Team Area name and click Save):

https://jazz.net/jazz03/admin#action=com.ibm.team.process.editTeamArea&itemId=_QxoE8OtOEeCjF_62kkTdSA&projectAreaItemId=_s_M8MMFIEdumDPUtna_vLA

My concern is,

We have loads of existing Team Areas across all our Project Areas with these characters in our environments.

Once we upgrade, we won't even be able to assign members to Team Areas having these characters. We first need to remove those invalid ones!

Furthermore, we can't create Project Areas out of our custom template because, as part of the Project Area initialisation, we use the 'Create Team Areas' follow-up action, and that fails because of these invalid characters.

I am wondering if we'll need to analyse the impact and remove invalid characters everywhere: Process Templates, Java API scripts, existing Team Areas across all Project Areas... and who knows what else.

Unfortunately, with the volume of data we have, it will take days, if not weeks.

Am I just being paranoid? or is there someone else out there with similar concerns?
