I will raise a compatibility issue, but it is bad enough to not think
about other things.
AFAIU, the proposed change will break whole export system? How would you
represent the AST of

First line
# comment
Second line


Currently, the above is parsed as 

        (paragraph "First line\n")
        (comment (... :value "comment" ))
        (paragraph "Second line\n"))))

Should we consider a comment as inline object? I suspect that such
change will cause unpredictable breakages all around Org and third-party

I am not sure if I like this idea. It seems fine, but I afraid that it
will complicate parser at some point. We may want to assign such inline
properties to the following object, which is already a pain for
affiliated keywords.
