I don't think Miles hated it, or if he ever did, not once Trane got fully tracked in. Miles could hear what was going on, and I'm sure felt tht losing Trane meant losing his front row seat to what was going on.
Truthfully, I don't think he found a similar kick in his own band for his own head until Wayne came on board. George Coleman was fine, but he wasn't Wayne.
For all the ican-talk and anti-icon-talk around Miles, never did he lose a very keen ear for things outside himself, nor an overriding desire to have a band, not just a jam group.
