Copy/Paste Speed Keyframes with Ctrl-C Ctrl-V (instead of just with 'Paste Attributes')

Using Ctrl-C + Ctrl-V to copy and paste does not work. Users have to copy the clip the speed keyframes are on, and then use the 'Paste Attributes...' option from the destination clip's context menu, deselect all attributes minus 'Time Remapping' to avoid mistakes, and then click 'OK'.
This is a terrible workflow because it is:
1. Inconsistent, since it breaks the basic copy/paste function that works on all other effects
2. Tedious, since it can require up to 6 steps vs 2
3. Completely illogical. A workflow that requires users to consult Google or the user manual just to figure out how a supposedly simple thing works is NEVER a good workflow!
Why does the speed effect break all conventions? (Including the inability to edit Speed keyframes in the ECP?)
