Almdahl’s law is a problem mostly restricted to scientific code and databases nowadays. Almost everybody else can just get more problems to solve in parallel, and split computing power between them. (Eg. you just run more instances of your web-server worker processes.)

And well, databases do not use glue code in high level languages (or at least, do not lock on it). So, outside of the scientific computing community, that's an almost complete non-issue.
