Hi Istvan,
I am a little bit frustrated to get full utf-8 pdf output support from lsmb

You're forgetting a major advantage: with this solution, we need to
maintain only a single set of templates and can scratch the LaTeX and
XeLaTeX versions.

There are a few disadvantages as well, though:
* wkhtmltopdf uses Webkit to generate the PDF; webkit is a pretty heavy
solution - so we're not replacing a heavy solution with a lightweight
solution; rather one heavy one with another
* If you *are* a (Xe)LaTeX wizzard, the output generated by (Xe)LaTeX looks
a lot nicer than what has been shown to be possible in HTML
* As you pointed out yourself later, wkhtmltopdf might depend on people's X
libraries being installed which is a pretty heavy solution for headless
systems running webservers.
The above being noted, I have to say I went to do the same reseach you have
just finished a few months back, because - as you - I run into the problem
that I think designing LaTeX templates is both too complex for
regular/non-tech/non-latex users. However, when discussing the subject with
Chris, he was concerned to break existing setups as well as replacing one
very heavy solution with another.
My conclusion would be that if we want to support both, we probably need a
good way for the admin to select one option or the other, with
autodetection logic to see if various options are available on the server.
