We agree that this feature is already well specified, and merely
thought that it should be clarified that this feature should be used
here.

We agree that length delimitation is attractive - indeed, essential,
if the object is to embed arbitrary binary data.

The alternative of a random separator string is computationally
unattractive if the software verifies that it is indeed unique, and
relying on statistical likelihood without verification was described
by some as "a fragile hack".
