It is not neccessary to make notmuch interpret tags as date - just interpret them yourself ;)
You can easily run your own scripts and modify tags/mails. So a simple solution might be:
* Add "snoozed" to your notmuch exclude_tags (see config file)
* To snooze a mail run in your mail client "tag +snoozed +snoozeby-10-days"
  or "tag +snoozed +snoozeuntil-2015-01-09"
* Your script (e.g. run as cronjob or after notmuch new) now 
  - queries for "tag:snoozed"
  - looks for snoozeuntil-* tag and parses the tag into a date. If date < now remove snooze-tags.
  - looks for (relative) snoozeby tag and transform it into (absolute) snoozeuntil tag.
(should be not too hard using e.g. the python or ruby bindings)

Of course you can use an own email header to store the snoozeuntil value.
With such a header it should be possible to use afew [1] for automated snooze-tag-management
instead of a hand-crafted script.

Franz
