Take a look at this. This is ABC and BU dev meeting/discussion. No technobabble. Real stuff. https://www.reddit.com/r/btc/comments/9voqg1/not_sure_who_to_support_in_the_upcoming_fork/
Is it relevant to my point:
Businesses voiced their need to see higher block sizes before starting years long software development on the BCH chain.
Yes, and they will get that with ABC along with the neccesseary optimizations to achieve gigabyte blocks. SV offers no concrete info on how they will fix the bottlenecks.
Ok so you have that info right in your link. Businesses need a clear pathway to higher blocksizes. 128Mb is kind of small but it may do for now. At least showing some progress.
