Microsoft Project Online is retiring: What you need to know

Shocking.  All I have read until now, is that PWA/Online will not retire - that's a harbinger right there, so I've been waiting for something.  I was hoping for PWA on SharePoint modern (vs current classic), maybe (hope beyond hope) it would integrate the fantastic agile Azure DevOps, I was not expecting Planner to be the replacement, what a joke!  Planner is A++ for my backyard project to build a dog kennel but not a serious complex project with dozens of resources, many shared across a portfolio or projects.  Planner cannot resource-level and that it only allows a one-time upload from MSP Desktop tells everyone something else... Expect MSP Desktop to be retired soon too!  Thank you Microsoft for years MSP helped me where projects delivered configuration not code.  Planner spells the end of a methodology described as 'Waterfall" if you are being kind, "Traditional' if you are not (my Grandad is 'traditional').  Yes there is 100% a place for Agile (Kanban, Sprints, Stories) where MSP is not good but there is 100% a place for MSP (Dependencies, Resource-levelling, EVA) where Agile tools are not good and then (the missing piece bridged only by the likes of Ceptah-bridge between MSP and JIRA as MS retired the API between AzureDevOps and MSP in 2019 - again why?!) where hybrid projects exist (the 80 in the 80:20 of projects).  Thank heavens we still have Primavera which may not be the same as Online but has other advantages such as Primavera Risk Analysis (an amazing schedule-based monte carlo analysis tool).  I hear Europe plans to decouple from Microsoft in the way China has (CrowdStrike have many considering following suit) perhaps their solutions will offer PMs a product that matches the 'voice of their customers' instead
