I do it this way because simply because of the ease. A 1 gal jug lasts me over 6 months easy. I have it by my calcium reactor and just eye it whenever I'm down there to make sure the line feeding back into the sump isn't clogged or the jug hasn't run dry.

I too tose BRS Magnesium sulfate and Magnesium chloride and then dose my system via doser (peristaltic) pump. My system is larger then most's so I dose a lot more then most do. I struggle to keep my MG up because I have clams and they do have a noticible uptake. I aim for ~1350ppm-1400ppm personally. As a result I dose in a continuous fashion; nightly.
Things to note; dose your Mg at a different time then your Ca or dKH additives. Add into a high flow area and do it SLOWLY. A Magnesium swing too high might take your system a LONG time to work through, barring water changes.
I dose my Mg at night and keep a buffer of around 4 hours before or after my Ca or dKH was dosed.
