Possible workarounds for the lack of inline editable widgets?

📝 Is there a way to mimic inline buttons and custom editable ranges?

So, there's currently no support for editable inline widgets. (Bummer!) Can we still achieve the below requirements with some custom event handling logic?

• Certain ranges of text contain placeholders (insert value here), which become fill-in-the-blanks when focused. Prevent user from starting a selection outside and ending it inside (or at least, prevent them from deleting said selection). Maybe we can leverage something like the Restricted Editing feature?
• Inline radio-button-like option sets. E.g. choose one of [small] [medium] [large]. User can click a button to toggle its state. Is this doable with inline widgets? Couldn't find a similar example in the docs. We'd need an inline "clickable" text button, not a popup dialog or floating toolbar.
• Assuming we could do these things, would they be compatible with collaboration+track changes using custom change descriptions?

(CKEditor5 ticks literally every other box for us, and we want to make it work. Specifically, we've not found collaborative track change editing anywhere else. Other controls tend to offer either collaboration, or track changes, or neither...but if there's one that offers both, we've yet to see it!)

You can actually create them by using a normal widget, giving it a class and styling it display: inline-block.
