I've just asked the Emacs maintainers about the patch.  As
we are already in a feature freeze mode, it's upto the
maintainers whether to include the patch in the next release
or not.

With your patch, the table of the third section (Others)
doesn't fit in 80-column with my font setting.  So, I
slightly changed the :align-to property.  Please check the
attached version (full leim/quail/indian.el) with your
environment.

By the way,

That's strange.  My Tamil Lohit font is Version 2.4.4 (older
than yours), and it displays the line for #0BB6 correctly.

The old table (full key sequence) contains the keys that are
not shown in the above tables; i.e. such alternate keys as
"aa", "~Na".  Are they really not necessary.

And, even if not necessary, the current code doesn't have a
mechanism to suppress it, and adding such a mechanism should
not be done now.  I'll put that matter in my todo list.

I don't understand why this is necessary.  Doesn't C-h C-\
tamil-itrans RET shows the top of *Help* buffer?
