Is Msol deprecated?

Could you elaborate on the current status of Msol and whether it has been deprecated? I've been hearing whispers in the crypto community about its potential decline in usage or relevance. As a seasoned practitioner in the field of cryptocurrency and finance, I'm keen to understand the implications this may have on existing systems and investments. Is there a need for users to migrate away from Msol or is it merely a rumor? Clarifying this matter would be greatly appreciated as it could impact decision-making processes and strategies in the crypto space.
