> Not something where each computer is a special snowflake with a developer fragmented experience about which libraries are even available on the system AIUI, these days you can just develop for Flatpack (if you're making a proprietary application) and declare your dependencies as needed. But do note that Flatpack is not a kitchen-sink "framework" or "platform": it's just something that addresses a number of fairly well-understood issues with the prevailing, mostly FLOSS-oriented, development model. (One reason that the issues are well-understood by now is that other "solutions" have been tried before, such as the LSB effort-- and found wanting.) This is key to decreasing complexity and making the system as a whole more comprehensible and surveyable. The commercial UNIXes you point to are far closer to your view of "each platform being a special snowflake", and big frameworks make this issue worse; they don't ameliorate it.
