Actually, you will be pleased to learn, this is no longer true. The
masking code is currently removed, and we will be releasing an 8.32
Release Candidate shortly that has no masking code. Once that is tested,
8.32 itself will be released with no masking.

Christian is going to work on implementing a runtime option that
explicitly requests masking. Apparently he intends to use this facility
himself. We will document it with suitable warnings (such as you put in
your message).
I hope now that everybody, if not totally happy, will be less
uncomfortable with this compromise.
