Doesn't the following work?
(defvar in-my-filter-p nil)
(defun my-filter (proc text)
(let ((in-my-filter-p t))
...))
(defun my-after-change-function ()
(if in-my-filter-p
...

Binding a non-command object (a process) to this-command looks quite
obscure and unclean to me.
Lots of commands look at this-command (and internally we copy it to
last-command etc). I could envision this change breaking code in
mysterious ways.
If really needed, the filter can do it
(defun my-filter (proc text)
(let ((this-command proc))
...))

Again, the filter can do that itself if needed:
(defun my-filter (proc text)
(let ((this-process proc))
...))
I don't think we need to provide a more general approach, at least not
before the release.
