Fair point. I often copy stuff across from one project to the next. But this point is most relevant when I'm using another language etc. for the first time and I'm tempted to try to retrofit all my previous best practices.

For example, I used to work on a mainframe product that dumped the address space to disk on a crash. Then it was possible to build all sorts of fancy tooling to analyse the dump. When I moved to a different platform, without those kinds of dumps, it was tempting to try to reinvent all this stuff, but it would have been a massive time sink (and would have failed too).
