Comment (by qdinar):

 but i think this thing is not designed very well and maybe it is not too
 late to change that, because rfcs generally are not very strict laws, and
 trailing dot is not widely used but used in "bind" dns server configs etc.
 i think
 1) trailing dot should not differ by its behaviour from other dots. first
 dot cannot create additional subdomain, so last dot also should not behave
 like it is itself something like a domain.
 2) also, ambiguity of domain without last dot is bad thing.
 3) and, trailing dot, especially just before slash, is not beautiful.
 -- i think, there are alternative ways instead of the trailing dot:
 1) example.com which is really example.com.mars. or
 example.com.something.mars. could be written "example.com..." and real
 example.com could be written "example.com".
 2) another alternative way: always using full domain like
 "example.com.something.mars" but only browser can show it in address bar
 as "example.com..." with something like tear or folding door icon or 3
 dots at end, and clicking that shows full domain.
