That's true.

Do you see there being any alternative option (not sure if Berner's Lee Solid can play a part here)?

A company called Velocity Labs has done a private blockchain where third parties issue credentials on a 'Career Wallet', but it's more on verification of employment, courses and such.

If you think about it, current solutions (including Linkedin's recommendations) are the same thing, just centralized.

There must be a way to change that.
