I think the problem is not elecraft rigs but amplifiers that have
unreasonably slow switching times.
10msec or longer is unreasonably slow and I think it's 'unreasonable' to
blame the manufacturer of the radio because the amp manufacturer saved a
few bucks and used a cheap, slow relay instead of a proper RF relay. 

None of my Icoms give me the ability to alter the key delay for slow
amplifiers either.

The correct approach is to mod the amp to improve matters. the other
option is to use the PTT input with a footswitch to take care of RX/TX
changeover
