I believe VHT80 (and VHT160) is allowed by current regulations in a
large number of countries, and that the current db entries are in fact
wrong by stating any upper channel width limits at all in the 5 GHz
bands.

For example, regulations in most CEPT countries are likely based on

 "ECC/DEC/(04)08 on the harmonised use of the 5 GHz frequency bands for
  the implementation of Wireless Access Systems including Radio Local
  Area Networks (WAS/RLANs)"

or a previous version of that decision.  Which is available here:
http://www.erodocdb.dk/Docs/doc98/official/pdf/ECCDEC0408.PDF

Quoting:

 "considering
  ..

  e. that the systems covered by this ECC Decision operate typically in a 20 MHz channel bandwidth, other
    values for the channel bandwidth are also feasible provided they comply with the relevant maximum mean
    e.i.r.p. and the corresponding maximum mean e.i.r.p. density limits;
 "

and the continues deciding the mentioned power and power density limits
only, without any specific channelization.  This document clearly allows
and anticipates both wider and narrower channels, and so does most
likely the national regualations implementing the decision.

The list of CEPT countries implementating this decision is here:
