This is an interesting question. I think it depends on the situation, You pay for memory so if you are getting near the cap in the execution of your function then managing the memory as you go may be beneficial but otherwise I don't see why you wouldn't just ignore it. I do have an open question weather the memory leak would effect subsequent runs of the function after it has been "warmed up" - https://serverless.com/blog/keep-your-lambdas-warm/.
