What is the enhancement in mind? How should it look and feel?

Add an API method so calling code could know if a tooltip could not be parsed reliably.

Please provide any additional information below.

Addons like RatingBuster could use this call to let the user know the reported numbers may be inaccurate.

How can LibStatLogic know if the parse is reliable or not? There are strings StatLogic doesn't care about(like OnUse, Procs, SetBonuses), strings that should be parsed but can't, and strings that are parsed incorrectly. LibStatLogic can't really tell the difference between the first two, so I don't know how this can be implemented.

As long as there are only parsed strings and willingly ignored strings, I think it it safe to assume the output should be reliable. In case there are non-parsed and non-ignored strings, telling the user that the information may be inaccurate seems valuable to me.

At this moment, all stats are reported as if everything has been taken into account, which is not always true. The warning would mean "do not blindly trust the summary about this item, something went wrong".
