Comment (by sbl):

 After I had a closer look at the t.rast.aggregate code, it seems that
 changes at library level would be required.

 Amongst others here:
 https://trac.osgeo.org/grass/browser/grass/trunk/lib/python/temporal/aggregation.py#L288

 I can try to implement that (and create a diff for a possible solution for
 you to review before I commit).

 Main question would be how to keep API stable when implementing changes
 with regards to multiple output.

 A possible option would be to use base name as is, if only one method is
 requested. And only if multiple methods are requested, the method gets
 injected in the raster map name (between base name and suffix/number).
 That would maintain current behavior but would open up for multiple
 output.

 Finally, a new standard parser option would probably be nice like
 G_OPT_STRDS_OUTPUTS, as there is currently no standard option for multiple
 STDS outputs(just input), see:
 https://grass.osgeo.org/grass77/manuals/parser_standard_options.html

 But this is something I cannot implement, and maybe it is not worth it if
 this is the only forseable case...
