The price of software is based on what the market will bear. Different segments of the market will bear different prices - e.g. consumer -v- corporate - and have different buying patterns - eg. single unit -v- volume.
Problem: How to extract maximum revenue across the entire market?
Answer: Pitch different 'versions' with different prices at each identified segment of the market with careful feature selection to minimise uptake of lower priced versions in segments targeted for higher priced versions.

Actually the VAXen were microprogrammed beasts and at the core you had a RISC processor. You could, at one time, buy some software from DEC to roll your own microcode. So instead of having all these macros in RISC assembler to perform common operations they just appeared as part of the micro-coded instruction set.
Are they fit for any purpose?
A sequence diagram usually only represents one path, out of many, through a use case. They don't handle exceptions very well and they don't handle message content particularly well.
All of this is evident in the examples given.
Why not use BPMN - Activity diagrams ++ - instead?
