As RichardF has pointed out, Potlatch2 sorely lacks any kind of data 
check. With the exception of unconnected road ends flashing aggressively.

One has to to take them as nagging-but-wanting-to-help tools rather than 
as commanders. Sometimes it says "road without name" and I go "oops, 
right, forgot that"; sometimes I go "shut the f&%$ up, if I knew the 
name I'd have entered it!".

I think doing something half-good and letting others (or the future 
self) fix it is perfectly all right.

With one exception: It is not all right to import crap hoping that 
others will somehow make it non-crap. The bar for imports is much, much 
higher than the bar for human edits.

That's because someone has imported crap and is now relying on you to 
make it non-crap. They shouldn't have done that. But if I were in your 
situation I'd ignore all the warnings.

It might not be a bad idea to have the validator run once data has been 
downloaded, and then when you upload, only have it show *new* problems 
caused by you. I'll float the idea on josm-dev.

I must say that I have rarely seen real people complain about things 
like you mention - crossing ways etc.; it's just the validator that does 
that. People will complain about other things.
