I am currently updating the draft, where the interesting challenge is to 
specify text that modifies the SRV RFC so that it's use of underscore 
names is moved to the new registry.

The current model in the _Underscore draft is to focus only on the 
highest level of _underscore naming, and treat any _underscore naming 
below that as local to the specification registering the highest-level name.

Given the existing variety of SRV use, I think it's worth having an 
exception to the model.  That is, rather than only putting SRV's _Proto 
names into the registry, also register the _Service names.

My reasoning is that it appears that only _udp and _tcp seem to be in 
current use as instances of _Proto, and it would be better to fold the 
range of existing _Service instances into this global _Underscore 
registry than to create an SRV-specific _undrscore registry.
