I don't think people should be told so directly to NOT use an official
Unicode character unless the character is actually deprecated.
Over the years recommendations about particular characters in the
standard have sometimes changed and no-one can see all possible uses for
characters or all ways that applications might use some of them.
But greying the chart area for deprecated characters and singleton
canonical decomposable characters seems to me a good idea.
As to compatibility characters, remember some of them, for example
spaces with varying widths, make essential differences in formatting.
The standard warns applications not to be hasty in unifyng compatibility
characters for presentation.
If it is not deprecated a character should be usable.
But some more obivous graphic indication would be nice to more obviously
indicate that perhaps a user should think carefully about using that
particular encoded character.
