1. You do not have to use M1, so why bother?
There may be someone else who finds it useful so why remove something that has been working since?
Plus, SysPrep may rely on that, dunno (never used that myself so I wouldn't know)2. The size increase by using the less memory-dependent lower compression seems to be negligible, unless you were down to single digit MBs already...
If you also include Windows updates, then you will hit the limit eventually, as these grow a bit each month.Also, WPI could easily been "exiled" on a second DVD or a network drive, if needed.
True, breaks the completely unattended installation but you could use a second drive if you had etc.3. Better by what?
Faster?
Yes.
Fragmenting the drive less?
No.Also, that is exactly what the Finisher does, cleaning up the archives afterwards...
4. The new auto-updater for the DriverPacks included in BASE kinda makes this a no-brainer.
There is virtually no difference for the user if they have got all packs at least once.
If it auto-DLs one pack or a handful, doesn't matter.
At the end of the day as the saying goes "you cant please everybody".
To point 3 tho m8 yes it would be faster as for the other things it works and works well so why fix something if it aint broke kinda thing? However making improvements is always a good thing... ok im not making much sense here but I hope you know what I mean.
