Yes; there are more flexible and more capable alternatives, as has been 
discussed on each of the previous times you've asked this question.

The OpenVMS APIs available for apps to access a distributed directory 
and to access and maintain settings are less well developed than those 
on other platforms, which is the crux of my comments.

Main memory on an Alpha runs at a fraction of the speed of main storage 
on recent-generation client hardware, and recent-generation client main 
memory surpasses Alpha processor cache speeds.

(Alpha EV7 L1 cache bandwidth: 7.77 GBps, versus recent-gen 204 GBps to 
main memory. Alpha local main memory bandwidth 4.6 GBps, versus 
recent-gen 7.4 GBps SSD read bandwidth. Etc.)

On OpenVMS, Eve and particularly TPU were built to script.

Most editors now are scriptable, of course. Just ask an emacs user.  Or 
a teco user.

And dedicated and portable scripting languages widely available, not 
the least of which are Perl, Python, and Lua.

Until and unless your preferred 1980s-era tooling ceases to work for 
you and your needs, I would expect nothing less.
