Your opinion might change if you worked on compat at Microsoft. The installed base is unimaginably huge. There are massive competing forces, i.e. the Windows team wants one thing but Adobe wants another because it breaks the last version of Photoshop. Or a change beaks a forms package used by Word but not by Excel. Or a decision hasn’t yet been made by the company to use GPU features that will be pop next year but not quite this year, etc. Well-meaning, dedicated players can spend months on a decision that looks wrong to you after the fact but wasn’t when the bug was finally closed.
