No further comments, so I'll close this one.

I think we agreed on the mailing list that
vs should not lead for noun-is words,
which typically are n, vs, adj-na, adj-no.
I'm not sure that discussion applies to on-min,
which typically are adv, adv-to, vs.

Daijr, GG5, etc.

(a) no problem putting うそうそ/ウソウソ into a separate entry. I added them here in 2013 on the basis of GG5, etc. simply pointing to うろうろ. I'll set up an entry for them,
(b) Yes, I've looked at that email thread on PoS/gloss structure for these beasties. It's the not-uncommon problem that Daijirin tags it as "（ 副 ） スル", but GG5 and the other JEs only have する/して/etc. glosses and examples.
Daijirin has an adverbial sense and two vs senses which match the two in GG5, so I'll propose a similar 3-way split.

I also don't think うろうろ and うそうそ 
should be in the same entry judt because 
thry are similar. うそうそ is way less 
common also (checked with a native speaker 
who had not heard of iy)

When this was discussed on the mailing 
list a year ago ("glosses not matching 
POS), I think the consensus was that vs 
glosses should not lead in these type of 
entries, even when vs usage is most common 
(as in the example of くよくよ）
