I've started looking into this.  Interesting consideration is that 
emacsql and sqlite have a bit different representations: in sqlite 
everything is a string, but emacsql will store symbols, numbers 
differently than strings, which are wrapped in the database with 
extra quotes to mark them as strings.  I'll try to keep 
compatibility between these versions, which really I think means 
that our use of sqlite has to support emacsql's way of doing 
things.

About the possibility of using one or the other, whichever is 
available, how would that work in terms of package dependencies? 
I don't think it's possible to have an OR dependency specified in 
the package-dependencies line in the source, but really only one 
of emacsql or emacs29 would be required.  If you have any insight 
into this, it'd be useful.

Great, that is what I'm doing.  When it passes tests, I'll let you 
know.
