There is a real problem with the default filter/sentinel, indeed.
Basically, add-function is a mechanism that allows combining functions
onto a "single function spot", so it provides the tool we need.
But another problem remains: for historical reasons (and for
convenience), the default filters/sentinels don't "do nothing". So in
many cases packages want to *replace* the default rather than extend it.
`set-process-filter' works well for those, until another package comes
along which needs to interact with it. Saying "use add-function"
doesn't really solve this problem, because we'll just replace
(set-process-filter PROC FUN)
with
(add-function :override (process-filter PROC) FUN)
which, just like set-process-filter, will override not just the default
filter but other filters added via add-function as well.
I haven't thought about how to really solve this problem. I'm open
to suggestions.

I don't have a good answer yet, sorry.
