Mmm, then my last question, after this I'll move to proj ;-)

See:

This is QGIS with proj6: As you see there are 2 options. The first one
being green 'numbered' (3). But the bottom one having a higher number
between brackets having a (4) between brackets?

Now /me wondering what these numbers are: because given your answer
above, the green one being 'THE one' :-) I wonder what this other
numbers are (I was wondering ordered by date/relevance or so)??
