Why no drop for mate?

 This is a follow up to a question asked in one the comments to a previous post.

I'm not sure this is the definitive reason why there is no "drop for mate" in Transfer (Bughouse), but at least in my memory, this rule was active in Canberra around 1983. In that year the Australian Junior Chess Championship was held in Canberra, and was organised by Nathan Stirling. On the opening day there was an introductory event, consisting of blitz and transfer.  For the transfer we were given the choice of allowing drop for checkmate, or not. IIRC the majority chose to allow 'drop for mate', and that was the rule adopted. I can remember winning at least one game using this method.

However in subsequent local events, the majority choice was 'no drop for mate'. At the time I assumed that both rules were equally used, and it was only after bughouse was played on the internet that it became clear that 'drop for mate' was the standard rule. However, Canberra has stuck with its preference, arguing that it requires greater skill to finish the game, rather than relying on a lucky break.
