As a personal aside nowhere in AIP does it mention "on climb" or "on descent" the proper terms are "climbing to" and "descending to" but that is being picky!
I don't think you're being picky at all, I agree wholeheartedly! I was taught early on that those types of transmissions should always end in
"ing". If one sticks with that little rule, you can't go wrong.
Some other examples...
"Joins crosswind" = joining crosswind
"Enters and Backtracks" = entering and backtracking
"ABC, taxies" = taxiing
"Lines up" = lining up
"Holds short" = holding short
Anyway, rant over.
