Well, maybe it sounded too strong, but... I'm not against the
improvements at all. I'm against the particular way they're
implemented. Sometimes similar things in JOSM are done different way,
and different things — in a similar. If I have enough time, I may try
to prepare some kind of analysis, not sure when I do that, however.

Practical achievements is one thing, I'm happy with the fact that users
can easily add things to JOSM styles, and I've used that feature
myself. I was extremely disappointed when simple things I expected to
work didn't just because JOSM implements them a different way.

I don't understand why there should be separete MapCSS styles for JOSM.
Or this is a single MapCSS which works across different renderers,
maybe with different support degree, or we have lots of local dialects
of it — why can' we have just one? We'd all benefit from that.
