There's now a progress bar for driver scans, but this doesn't include some of the firmware/bistream upload steps, possibly because they don't happen at scan-time. PV should probably also have progress bars for device opening and acquisition start if it takes longer than a certain amount of time.
Indeed but there's no libsigrok API for this, so it's either "done" or "not done yet", meaning that there can't be an indication of progress as such.
