I’ve got some experience as Head of Cyber/InfoSec at a couple of startups/scaleups and I see this as potentially useful in a bunch of ways if broadly adopted. It establishes a baseline both for our own products and our suppliers, attests to stuff that actually affects how we integrate with and operate a third party product (ISO 27001 gives me no clue whether you support SSO, have viable logs that I can actually ship to the SIEM etc.) and hopefully simplifies both the due diligence we do on our suppliers as well as that done on us by our customers by allowing us to reduce a good chunk of the product feature questions to “does your product meet the MVSP standard”.
There was a pretty useful discussion of it on the Google Cloud Security podcast a while ago: https://cloud.withgoogle.com/cloudsecurity/podcast/ep114-min...
