[QGIS-Developer] [Qgis-developer] Adding default OSM backround maps

Hi Stéphane,

Your suggestion may complement or be an alternative to the default OSM
background maps.

Regarding the implementation of the initial proposal, it is not
difficult and have been done in PR#4352. It is basically one button to
add another layer to the map.

Creating a new vector tile service, provided by QGIS, seems quite more
difficult to me. We need to maintain a mirror of the planet. This means
a lot of resources (hw and ops).

Developing one style is not difficult but one that everybody likes is
much more difficult. We would end up as OSM did, with several styles,
for different users. But if the render is on the client side, there is
no problem to maintain more than one style.

In summary, providing the tile service seems more complicated to me, but
this can be further explored. If you would like to try it, I can help.

Regards,

Jorge Gustavo
