Never said I was.  But deleting incorrect information is better than
leaving it around, even if it isn't as good as correcting it.

How would I even go about checking?  Is this really something we
should be doing every time we make a bridge?

Yes, there are situations where one way will correspond to two or more
TLIDs.  But probably 95% or more of the times I deal with TIGER ways I
am splitting ways, not combining them.

In any case, I disagree that it's better to leave information you know
to be wrong in rather than deleting it.  Perhaps that's our
fundamental disagreement.  If I see something that's wrong, I'd rather
delete it than just leave it.  If there were a relatively easy way for
me to fix then I'd do that, but with tlids I don't know of any
remotely easy way to look up the right information.

As for tiger:name_base, tiger:name_type, etc., if there's someone
that's using that information, we definitely should take it out of the
tiger namespace.  I'd be happy to move it from tiger:name_base=* to
name_base=* instead of deleting it, if someone is using it and would
take 5 minutes to put something up on the wiki announcing it.  If it's
useful, then it's useful for non-tiger ways as well as tiger ways.
