The point is that Bitcoin Core is as much of a fork as Bitcoin Cash.

You're mixing up soft fork with a hard fork and implying that soft fork is somewhat better, when in reality it is just technical concept and has nothing to do with it.

Actually in current situation we already have example, the soft fork (SegWit) implements a complex mechanism to add segregation witness feature and allow for off-chain transactions.

The change in Bitcoin Cash is simply raising the block limit to 8MB. In fact initially bitcoin had no limit for the block size and the limit was added to prevent DDoS.

That limit was meant to be increased as there would be higher demand.

That is not true. Initially Bitcoin crashed when blocks went over a couple of hundred kilobyes. Satoshi put in this hard cap when this inadvertent limit was fixed.
