Thank you for an additional investigation.
However, I think that you may always make all tag files.

When the cost to keep an old rule exceeds the merit, you had better
change the rule itself. New rule is like follows:

o All tag files (GPATH, GTAGS, GRTAGS, GSYMS) must exist even
  if some of those are empty.
o The format of GRTAGS and GSYMS is always the same.

Things become simple by this rule,

Though command layer plug-in parser follows the old rule,
command layer itself will become a past relic in near future. :)
