I know nothing about WebSVN internals, but if that's the only issue, 
PHP's memory_limit setting should allow avoiding such as issue: 
https://www.php.net/manual/fr/ini.core.php
Do realize that this setting only affects a single script's usage though 
- it will avoid one script execution going berserk, but if we really 
want to set an overall WebSVN limit of 4 GB for example, we probably 
need to set memory_limit to - say - 512 MB - but also the max number of 
concurrent requests to 8.

I personally used WebSVN for translation issues a few times. I wouldn't 
have helped as much without it. I would find it unfortunate if 
translations could no longer be viewed from the web. I would consider 
that issue as somewhat strategic, since many start contributing by 
getting involved in translations... and a web access to translation 
helps getting involved in translation.
