The number of pages is saved as two bytes in the DVI file header. This
means that there is this limit of 65536 pages that cannot be changed
without breaking of backwards compatibility, so it is unlikely to happen.
Is it just a matter of changing some hardcoded number

This is the limit of TeX, we cannot change it from the inside of TeX4ht.
But you can use larger page sizes to work around this issue. Like paper
height of 575 cm:
\usepackage[paperwidth=100cm, paperheight=575cm]{geometry}
This is the maximal size before I get dimension too large error.
I hope this workaround doesn' cause other issues,
Best,
Michal
