Once a 7uN is forked from the mainline 7u development, it will  
"inherit" the Hotspot version from mainline.  E.g. in the current case, 
where HS22 is the 7u mainline Hotspot, when 7u2 forks off for 
stabilization, 7u2 will remain Hotspot 22, with increasing build numbers 
as we do stabilization

The mainline 7u Hotspot will bump up in Major version at that time (e.g. 
it will go to Hotspot 23) - actually, we'll bump the Major version in 
the Hotspot development area (hsx/hotspot-main/hotspot), and the next 
push from there in 7u will increment the Major number (and reset the 
build to 01).

Generally speaking, Minor number bumps will be reserved for 6Update use, 
or JFB (or CPU) releases of 7Updates.
