Yeah, either that or "architecting something new looks better on my resume than using an existing solution."
However, I'm sure some folks would be tempted to add something like "designed and implemented a distributed task scheduler and execution engine for generalized asynchronous jobs utilized by X number of devs across Y teams" to their resumes.
Because I can't imagine why it would award that relevance. It's right there with "implemented function to reverse a list because the stdlib had a bug".
