dret has just created a new issue for 
https://github.com/w3c/tt-profile-registry:

== Registry Stability ==
it seems that the current policy does not make any assertions about 
the stability of identifiers and their meaning. this means that it is 
possible that identifiers get redefined by registry updates. many 
registries avoid this kind of semantics shift by disallowing updated, 
or only allowing updates that deprecate values. the reason is that 
typically, registry contents will be used to write code and and then 
any changes to entry semantics will break this code by redefining the 
meaning of an existing value.
https://tools.ietf.org/html/draft-wilde-registries-01#section-3.5 
makes the point that it is a common pattern to disallow updating 
semantics. if that isn't done, i would recommend to add a note to 
developers that identifier semantics may change, which probably will 
break implementations, even though there is little they can actually 
do about it.
