I believe they have been on Agile for a long time now. They do show the sign of Agile, including the numerous small bugs and the occasional regression .Hmmm, that sounds like an agile development practice. Didn't FDev originally try that (around 1.1-1.3) but lots of people moan about "too many patches"? However I really would add my voice to lots of regular patches, given they must be on a multi-branch strategy now ((at least) one for Will/Adam's "tactical" fixes and Interstellar Initiatives, and more for the longer term fixes) there are advantages to regularly consolidating your bugfixes ;-)
I wonder, if FDev can have multiple update branches, one for people ok with frequent updates and one for the others.
