I asked around for some feedback, but no one was interested in that

Did you announce it anywhere? I haven't heard about such plugin.
I certainly asked in Munich at our regulars table and some mappers I
personally know from Thailand.
You can give it a try If you like:
get the plugin here:
http://downloads.osm-tools.org/GPSBulkLoad/
Usage:
Select File/Bulk load GPS
Then the familiar Area selector opens. Tick "Raw GPS data" and select
your area of interest. I recommend starting with a smaller area and then
get gradually bigger as you get used to the amount of data loaded.
The demo contains data in this area:
sqlite> select min(lat),max(lat),min(lon),max(lon) from GPS;
56000010|204099980|973001964|1095999830
While loading is already quite fast, it does not yet accumulate the data
but loops and does single queries. If you request huge areas with sparse
points the waiting time for the connections can get longer than the
transfer, depending on internet speed.
Final version would accumulate the data.
Also caching not yet activated ;)
It's a simple prototype to see how it would feel to get just the
anonymous GPS points without speed information (lack of timestamp and
track).
For some areas it's useful. In Thailand we got a bigger GPS donation
from some motorbike forum, so it can happen that there are GPS tracks
without any OSM data around. Virgin territory awaits you :)
Also be aware that JOSM is getting a bit slower after the first million
of GPS points loaded.
With the final plugin this would be no problem as the data is cached, so
no need to keep the layer loaded too long, just reload when it's needed.
