I believe the data mesh claim is that as well as the operational API exposed and supported by some given domain team, the domain team also gets a new goal of exposing and supporting an analytical API to deliver a data product to potential consumers. For this to happen, an organisation would need to value this new objective -- perhaps comparably to operational objectives -- and fund and resource it adequately. Arguably throwing enough budget and appropriately skilled headcount at it might address points 1, 2, 4, 5. But, it's not obvious it actually makes sense for an organisation to value analytical concerns at a similar level to operational concerns, with similar resourcing. The value to the organisation of building and maintaining analytical APIs to serve data products is likely to be considerably less -- perhaps by one or two orders of magnitude -- than the value produced by actually performing and maintaining the core operational function. If the stars align, maybe in future the analytical data could be used as input to an optimisation project that improves some key metric of the operational function by 10% or 1%. How much is it worth paying to have the possibility of an outcome like that in future? Not obvious, really comes down to how valuable a 10% or 1% lift would be, and how much it would cost, needs some kind of business case. Not obvious that resourcing analytical data APIs owned by arbitrary domain teams everywhere is a sound investment for the business.
