Thanks for the feedback @c3rnst !
So if I understand correctly, since I am doing a time-based grant (which used to be a core contributor grant?), it is ok if I don’t provide milestones but rather describe the scope of work as described here.
If this is correct, I think it makes sense to put in the template the Type of Grant above the Milestones part and list the different types of grants since they are new (as far as I understand).
