Unicode currently allocates a large number of PUA codepoints which lack any interpretation, including the entire plane 15.

I was curious if there has ever been discussions within the Unicode Consortium of allocating new PUA ranges which had their interpretations partially defined.

In particular, it would be useful for those dealing with scripts which are not currently under consideration for inclusion in unicode if there were sub-ranges reserved for RTL characters, or subranges where codepoints are divided into uppercase/lowercase pairs even if the characters themselves are left undefined.

Does anyone know if this has ever been considered?

It has been suggested on the Unicode mailing list 10 years ago, see https://www.unicode.org/mail-arch/unicode-ml/y2011-m08/thread.html#124, but it seems there was no consensus to allocate such a PUA range.
