Most CW ops that do not use full QSK do operate semi-QSK. And in that case the 
delay between the amp key signal being asserted and the t/r relays closing and 
settling reliably is just as critical as full QSK. Many non-QSK amps are 
deficient in this area, which leads to hot switching, chopped initial 
characters, loud initial transients, etc.
There is also the annoyance of the noise in the shack from clunky relays, also 
an issue with SSB VOX.
Personally I use full QSK less than 10% of the time, but I would want a 
QSK-capable amp even if I never used it.
