But that drop all \skewchar, \textfont and other definitions as those 
commands use fonts at time of assignment. So if I redefine font \tenrm 
then \textfont will still use old font...

It is slightly modified, but still plain:

http://texdoc.net/texmf-dist/tex/csplain/base/csplain.ini
http://texdoc.net/texmf-dist/tex/csplain/base/csfonts.tex

It basically replace cm* fonts with cs* (cs* are just extension and 
fully backward compatible with cm*), set A4 format, load also Slovak 
hyphenation patterns and in pdfTeX uses encTeX for UTF-8 support. 

So I would say it is still plain, just for Slovak texts.

But in LuaTeX for loading cs* fonts is needed your fontloader with 
TFM+PFB support, for original Knuth's cm* fonts not.
