Why not?  If you don't want bare WikiWords to be matched, just set

muse-wiki-use-wikiword to nil.

I'm really not a fan of making a generic regexp that matches both

explicit and implicit links.  It was a lot simpler to make Muse do

what it does now, which is as follows.



Term :: a "handler" is a routine that cycles through a list of

functions, passing the link to each one that is called



 - a distinct regexp for explicit links



 - a handler for explicit links that can "intercept" the links before

   they are put in final form -- if no function handles the link,

   still accept it



 - a very generic regexp for implicit links, which is only used by

   muse-link-at-point



 - a handler for implicit links detected by this generic regexp that

   calls a customizable list of functions -- at least one function

   must provide a match, or the link is ignored

That could potentially useful.  Or even:



(defvar planner-date-regexp

  "\\([1-9][0-9][0-9][0-9]\\)\\.\\([0-9]+\\)\\.\\([0-9]+\\)")



and use (concat "\\`" planner-date-regexp "\\'") whenever the entire

string must be a date.
