1. Before:

> > Finding nearest areas...
> > ^C
> > real    317m9.500s
> > user    0m12.230s

2. Skipping the v.db.dropcol step I get:

> 292317 records updated
> real    0m47.338s <~ !^1000
> user    0m23.100s

3. After latest changes, that is without skipping the "v.db.dropcolumn" in 
grass7, the same command:

292317 records updated
real    0m54.029s
user    0m25.830s


Just a (small) bit slower than before.
