None of these seem all that 'trendy' to me. The real trendy approach would be something like leaping directly to a hybrid userspace-kernelspace solution using something like https://github.com/CloudNativeDataPlane/cndp and/or the https://www.kernel.org/doc/html/latest/networking/af_xdp.htm... addressing that the former is built on. Very interesting stuff, don't get me wrong there - but hardly something that can be said to have 'stood the test of time' like most boring tech has. (And I would include things like eBPF in that by now.)
I have similar examples from other projects of using io_uring and af_xdp with similar outcomes. In 2020 when the ebpf decision was made it was pretty new an trendy still too... in a few cases each of these choices required us to wait for deployment until some feature we chose to depend on landed in a mainline kernel. Things move a bit slower that far down the stack so new doesn't mean "the js framework of the week", but it's still the trendy unproven thing vs the well-known path.
The point is still: evaluate the options for real - using the new thing because it's new and exicting is equally as foolish as use the boring thing because it's well-proven... if those are your main criteria.
