A similar function is part of the TW core since V5.2.0 See: https://tiddlywiki.com/#HTML%20in%20WikiText : Pragma Comments
! Pragma Comment
This plugin allows developers to add comments outside of "macro definitions", so they don't waste any time during execution. This is _not_ possible with the default wikitext
\\ comment comes here till the end of the line
\define test() Hello World
! WebDav last-modified Plugin
This saver uses last-modified and if-unmodified-since HTTP header attributes, to detect file inconsistencies, which allows the server to activate server-side file compression.
The core PUT saver uses etags, which don't work, if server-side file compression is active.
! Edit Tabs Plugin
This plugin adds internal tiddler links to every tab if selected. It adds a setting to the ControlPanel: Settings tab, that allows you to activate "non system" tiddlers directly in edit mode. This comes in handy, if you are creating a lot of new stuff.
