I like your idea more than my similar attempt:
Max Nikulin to emacs-orgmode. [PATCH] Intra-word markup: \relax. Fri, 28 
Jan 2022 19:12:51 +0700.
https://list.orgmode.org/st0mk5$fnv$1@ciao.gmane.io

The good point in your patch is that \- is still work as shy hyphen 
(that, by the way, may be used in some cases instead of zero width 
space: *intra*\-word). On the other hand I have managed to find a case 
when your approach is not ideal:

*\--scratch\--*

<p>
<b>&#x00ad;-scratch</b></p>

"\--" are added with hope to suppress bold text and keep asterisks.

I expected possible problem at the border of "-" and "$", but 
fortunately the following works well

/pre/\--$n$\--*th*
