I wonder how important matching is for a pure

You are right, not at all.

Only the coax cable currents are not considered
in the simulator diagrams, there might be an influence.
Therefore matching is important :-)

You should have stopped writing at the first thought. CHOKING is
supremely important, and is a benefit found in good matching design.
Choking can be achieved without matching, however. And choking will
be needed at least at the feed point, and again a quarterwave down the
line.
