The idea is not necessarily dumb, but there are many different file
formats for ebooks. If somebody wants to work on that, they first
need to decide which format they want to support. See e.g.
As a matter of fact, two of the ebook formats listed on that page
are already fully supported (PDF and PostScript); for now, i'd say
simply use PDF as your ebook format of choice, and you get a very
high quality ebook straight out of groff.
Another ebook format listed on that page is half-supported: HTML.
HTML output quality from groff is poor, though.

That is true for some groff developers, but not for all.
For example, i'm very interested in ASCII and UTF-8 plain text

You are kind of right. *If* somebody picks an XML-based format to
implement, the right approach is almost certainly to only support
one specific macro set (and mom would indeed seem a good choice)
and not use the groff program at all, but translate directly from
macros to XML, thus preserving all the structural and semantic
markup, which would be destroyed if the input were first run through
groff(1). Just like it was done with mandoc(1) for mdoc(7), man(7),
tbl(7), and eqn(7).
It would be a big task, though. For comparison, when two people
worked on mandoc, it was ready for production after about two years,
and right now, after ten years of development, there are still
things to do. What you are asking for is significantly more work
than that because mom is a larger and more complicated macro set

Grohtml is a failure on the most basic architectural level.
Making that work is probably almost impossible.

I can't speak for the other developers, but i very much doubt that
any of them will pick up such a large task right now. Basically,
regular maintenance work is what groff developers have time for
nowadays, but not much more.

The idea is not specific enough for that, nor would it make sense
to make it more specific before somebody speaks up who actually
wants to do it.

It would be nice if it were easy to find people to take on open
source programming projects, but the reality is it isn't easy.
Those who are qualified and interested typically already have their
own ideas what they want to do, and those who aren't even able to
make up their own minds (such that they resort to asking others
what to work on) typically aren't capable of doing anything serious
in the first place.
