It is a nice idea – but
The main problem I do have with an :except filter run prefix as comment is, that it is based on 2 potentially wrong assumptions.
- No comment made, that way, will ever be a tiddler title
- Users can identify the difference between an :except filter run and a comment
This assumption will fail whenever comments get shorter. eg: -[[TODO refine]] – There is a high chance that this “comment” will be a valid tiddler in the future.
There is no chance to see, that it is a comment, even used like this -"TODO refine". I personally do use single double-quotes in some filter expressions.
This was the main reason, why I immediately did create a proposal and 2 different PRs at GH.
Especially, since Jeremy already created an issue 2 years ago.
So there is a high chance, that one or the other version will be pulled into the core.
