indeed, I am trying to keep all parameters in four tabs (which are
visible by default). I don't feel familiar with v.surf.rst. Could you
suggest reordering parameters to less tabs?

It was a bug, fixed in r36250 (devbr6) and r36251 (relbr64).

I would suggest to replace in all modules which uses 'layer=0' with
appropriate flag.
