> My experience with people reading interactive maps is actually the opposite. A limited set of discrete scales can make maps much more accessible and the inability to easily reproduce a previous viewing situation precisely in scale can be extremely irritating.

Sure, styles optimized for specific scales can make those scales more information-rich and efficient, which ultimately helps the user. But I was referring to the user experience while zooming and panning. If we were considering making the left or right sidebar animate in smoothly, I would raise the same argument (though it would be much less of a priority).

Getting stuck on a fractional zoom level is certainly irritating for those of us who design map styles. Currently, the user can only return the dashboard map to an integral zoom level using the keyboard: maplibre/maplibre-gl-js#6872. The map on the homepage is synchronized with the URL, so it would be possible to manually edit the URL to remove the fraction. Not an intuitive workaround either way!

Regardless, the migration to MapLibre (#6234) is motivated by other considerations. Smooth zooming would be at best a nice-to-have but not something we desperately need in conjunction with the raster layers.
