Correction:
This applies not only to GUI as I thought, but to v.surf.rst in general. Why
do we have a default for zcolumn? Should there really be one?

we put it there as a convenience because flt1 is the default column name if you use
v.in.ascii to import the point data (at least it was the last time I tried it).
This way I can import and interpolate the way I did it
in GRASS5 without checking the column names. I don't think this is a bug, this is a feature.

The zcolumn should not have default value.

Why not? In interpolation 2D data must always have an attribute (floating point, no categories). This makes sense to me.

No other 'column' option has a default value.
Column name can be any word, v.in.ascii without definition
of column names is just one possible way to create data
+ it creates columns dbl_1, dbl_2 etc.,
+ if you import x|y|val with v.in.ascii, the column names will be
dbl_1, dbl_2, dbl_3 so it would be necessary to have default
value for z dbl_3. Simply default value for input column name is
not a good idea.
