8.5 is feature frozen, so not likely to happen

if it goes into the CVS head now it goes into 8.6b2...
IMO delaying the merge post 8.6b2 will significantly reduce the amount
of testing the cocoa port receives before 8.6 goes final, so I'm not
too keen on that

services, no, were you thinking of a Tk app as a service consumer? for
what kind of services, modification of text selection in a text
widget?
there is no provision for that sort of thing in the generic tk text
widget code ATM, so it would need generic (TIPable) changes, feel free
to write something up (e.g. [clipboard] based), it would probably not
be very hard to add once a design is nailed down (services API is
pasteboard based and very similar to the pasteboard use in the
clipboard code in TkAqua Cocoa).
Asian language text input does not work currently, along with other
advanced cocoa text input features, mainly because Tk text input is
based on raw key events and we do not use the full cocoa text input
pipeline. It is not clear to me ATM how we can preserve Tk's
requirement to bind to raw key events (with any modifier) without
relying on raw key events.
Cheers,
Daniel
