Doing everything explicitly can get to be annoying, especially when it comes to what you had to do before without Vulkan's VK_EXT_shader_object.

It's clear that some stuff should be implicit - most types in programming languages, for example; needing to specify a struct type and then the struct itself can be annoying - and other stuff explicit, like low level operations.

Returns are something that usually fall into that "implicit" category. Why should I do let a = function(); return a; when I can just do function()? It's shorter, simpler, and I don't waste keystrokes.
