Should multitables be nested ?

Hi,

I am currently working on the multitables support which is
a bit broken (for example an @item within text on a line is 
unsupported, more @tab than table width are accepted and 
multitable begining isn't recognized in some cases). 
This is so because multitables are handled like regular
tables, with a hack to make @tab disapear and it is wrong in 
some cases. I am going to fix that, but I have a question before.

Currently it is possible to nest multitables. I suspect this
feature is not really a choice but merely an nice consequence of
handling multitables like tables. makeinfo and texi2dvi break
on nested multitables. The question is: should we handle nested
multitables ? It is technically possible, but is it really wanted ?
Maybe handling them but issuing a warning should be the more
appropriate behaviour ?
