You are missing the point that a lot of people buying the Vero are new to Linux and don’t know how to do NFS. There are a lot of posts here that show this is true, and even people who understand it a bit sometimes make mistakes.
Having a file that guarantees that the best (for OSMC, at least) options are always used by default, even if the compiled-in options to mount.nfs are changed makes supporting this easier. This won’t prevent users from setting options manually in fstab, as those options override any matching ones in /etc/nfsmount.conf.
Next, having a file with a skeleton for the options in a more readable form than really long fstab lines makes it easier for users to change something globally for all their mounts (the most common use case, as most users have one NFS server), but also allow easy changing of defaults for a particular server. Setting options for individual mounts in /etc/nfsmount.conf is a bit silly, but that can be done also, for users that want just one file to edit.
It’s easy to forget some of the more obscure options when doing a quick add of a mount to fstab (like “minorversion=1” is required when mounting a Windows NFS 4 mount), and nfsmount.conf prevents that. It also allows you to put commented out “how to’s” right in the file (again, for special cases like Windows NFS, or if you know specific NAS implementations require special options), and users can be told just to enter their server name/IP address in the “Windows NFS” section and remove the comment hash marks.
This setup would allow you to give help to users like “replace ‘yourserver’ in the following line with the name or IP address of your server, and ‘yourshare’ with the name of the share”:
yourserver:/yourshare /mnt/myfiles nfs defaults 0 0
No long, confusing options to mistype or misread, and easier debugging when they post their fstab entry here (“Is that the right server/share name?” “Have you tried it by IP address?” “Did you create the mount directory?”).
So, no, for NFS, I don’t need any help, but a lot of other people might appreciate you making it easier for them, and you might like having less questions, or more questions that can be pointed to an FAQ.
