The message and comments actually raise more questions. While they might not completely remove the i386 libraries, they will be marked as "legacy" and will not see any updates (frozen 18.04 versions). But what about security fixes? The thread is an interesting read, but also feels like this was made as a uninformed decision; were the consequences realized? And if they were, why is this not properly communicated? Their userbase and 'partners' need to know and understand what this means to them. Reading the response from Valve, this clearly isn't the case.
