So, basically: performance accessing files on the host from the VM over NFS is not great, and this is bad. performance accessing files in the VM from the host over NFS is not great, and this is ok . Kind of self-contradictory

It isn't if you’re more interested in better performance during runtime. I can tolerate a certain delay when my IDE writes to a file on the host but I need the best performance when my app is running.

Edit: the point here is about shifting the area of compromise. I would very much prefer to compromise on IO performance when writing/reading files with my IDE rather than sacrifice the web server performance on the guest.
