Is javascript fingerprinting becoming obsolete?

Okta recently sent out an email to admins about changes to their new device detection strategy. According to them:

Due to browser advancements in anonymous web browsing, JavaScript fingerprinting techniques are quickly becoming obsolete. Google, Mozilla, Microsoft, and Apple are working to improve privacy, gradually resulting in inaccurate fingerprint detection.

How accurate is this claim that javascript fingerprinting techniques are quickly becoming obsolete? This would have a major impact on multiple industries, including marketing, security (as evidenced by this email), and fraud detection.

I’d personally love to see all browser fingerprinting be hamstrung but I have to doubt that it’s going anywhere but forward.
