Good progress :-)

I've always been surprised what users end up using. Who would ever care about
the value in a field's padding, for example? Well, I have--because the value
not being zero was the indication that "the bug" happened. Because the value
of the padding bytes was a filter I could find the packets I needed with a few
keystrokes rather than painfully looking at 100,000 packets (okay, I would
never do that, I'd run the output of tshark through grep, but that would still
be a pain compared to just running a filter).
Filterable items can also be used in custom columns (as Stephen mentioned), I/O
graphs, and all sorts of other cool features--the stuff that make Wireshark
great. Just decoding to text weakens all that.
If you're worried about having too many filters, check out X11:
grep -c '&hf_' epan/dissectors/x11-register-info.h
7101
I'd still like to see most of the new add_text()'s turn into add_item()s (or
other filterable things). (Fixing the old ones would be a bonus, of course.)
That being said, I won't reject the patch in case another developer doesn't
feel as strongly as I do.

Fair enough...
