@datejada @gnawin Here's our main epic. Feel free to change bullets into issues as they're created.

Added #965 because I found big Ms in MGA formulations.

The demand responses can be done, both EV and profile. There could be further methods, but no one has reported any great need for those. So, I'll mark them as done.

https://github.com/spine-tools/SpineOpt.jl/issues/677 should be sub-task here. (And Manuel has already done something on that)
