 I have a foot switch but only use it generally on Sunday of a weekend contest.  That's when my throat needs unfleming or whatever that iswhen your voice is overworked but I always just use vox if possible.  In the older days it was PTT but with a desk mic and not a foot switch.But my foot switch is always there if I need or want it, just have to drag it forward a little and place it in the "spot" where my foot can get to it.
I'm not a phone guy but when I bought my K3 in 2009 I opted for the dvk and that is more valuable than a footswitch will ever be.  Too badI only get to use it twice a year in ARRL & CQ dx phone tests, hi.

Hi Dimitry,

I strongly agree. I HATE foot switches, because I'm very poorly
coordinated. :) I've never used anything but VOX in my own station for
any mode, and I do RTTY, CW, and SSB contesting, run FT8, JT65, JT9,
MSK144 for small signal work. With every rig I've owned since 2003 (when
I had time to back on the air) I've been able to set the delay between
transmitted RF and the DC signal to pull in the TR relay for a power amp
to the value that my amps have needed. The high quality, well designed
amps I've used have never needed more than 8 msec.

That's me. Everyone is different. :)

73, Jim K9YC
