Thank you Even and Frank!

I will likely adopt the `osmconf.ini` method.

@Frank, I would go a step further if time permits. A function or script that
takes something like `layer=lines` and
`keys="track,footway,bridleway,path"` as input parameters and outputs the
custom configuration file.

From reading the driver's manual [0], there is a hint about the spatial,
filtering resulting in lines or polygons missing vertices. Is this a/the
reason, to stick to `osmconvert` for extracting areas of interest?

Thank you for your (invaluable) time, Nikos
