I should start off with the fact that we are currently still running the CCL 50.3 library.
Being in the residential sector we have many jobs that have 8+ pulls per room or job. We have one now where we have 10+ pulls in only 3 different rooms.
For us, in residential almost all the pulls would be custom or unique to the job in question so building every pull into the library doesn't really make sense. Because of this I can't justify the time to have the pulls in the dropdown list ready to go and to be applied.
