"saturate the load very slowly"
It must be poor programming of the software. Nay - not poor programming - shoddy programming.
I remember reading absolute yonks ago, that the aim by certain manufacturers (Bosch, Hoover, et al) was to 'wet out' the load as quickly as possible - to reduce friction damage.
And I think some manufacturers could improve the wetting-out phase further still.
For example, if a machine has a recirculation pump, then why not switch it on too, say five seconds after the machine starts to fill? That way, any detergent flushed from the dispenser drawer would be immediately mixed, dissolved, and injected back into the load, in quick fashion, rather than languishing in the sump.
The optimum water level/absorbency problem would also be achieved much quicker, without all these 'stop-starts' which some machines seem to delight in doing.
Frankly, I could do a better job of programming the machine's software. In fact, I think most of us on here could. I just dunno what goes on in the heads of some machine designers.
Regarding garments, personally, I turn large garments inside out (t-shirts, polo shirts, jumpers, trousers and shorts). Smaller items get washed 'as is'. But sometimes, it appears to be down to the type and weave of fabric. Some will pill/bobble more than others.
