...whereas the STOMP 1.1 spec explicitly forbids that.

We use a single parser to parse all versions of STOMP. We don't want to 
start parameterising the parser with the STOMP version - way too much 
complexity and hassle. So the question is whether we could construct a 
lenient parser that accepts unescaped colons in header values across all 
STOMP versions w/o introducing any breakages. I have filed a bug to look 
into that.

Matthias.
