Having before now helped replace a (very naive, this is -not- an attack on golang) 8 core golang bulk pg data loader with a single threaded perl script and got about a 6x performance improvement, "high level languages wielded by somebody who understands the limitations of the VM" are really much more capable than a lot of people think. Of course, "lower level languages wielded by somebody equally proficient with that language" will still be way more performant, but sometimes velocity of development wins out over straight line performance when the dynamic code is fast enough for the uses cases you're currently supporting. Wanting to rewrite components in rust is both completely logical and also (and I mean this as a compliment) a Nice Problem To Have.
