com.google.android.trichromelibrary - An app that gets installs multiple times .....what's the point?

As I understand com.google.android.trichromelibrary is supposed to be a webview replacement in android 10+
find /data/app -type d -iname "*trichrome*" -exec du -hs {} \; 70M /data/app/com.google.android.trichromelibrary_475808733-hbwaY4KXRVEdoKq10mzzfQ== 71M /data/app/com.google.android.trichromelibrary_484407333-96Dwrx11cIuvXstExOmMTA== 72M /data/app/com.google.android.trichromelibrary.dev_495100733-Znh6eO5SOBu_ORYXeXI2zw== 71M /data/app/com.google.android.trichromelibrary_484408833-7teK0Hyij0I9yq5l070LmQ== After uninstall
# find /data/app -type d -iname "*trichrome*" -exec ls -ald {> drwxrwxr-x 4 system system 3488 2022-03-23 18:10 /data/app/com.google.android.trichromelibrary_484407333-96Dwrx11cIuvXstExOmMTA== drwxrwxr-x 4 system system 3488 2022-03-31 00:38 /data/app/com.google.android.trichromelibrary_484408833-7teK0Hyij0I9yq5l070LmQ== 4 instances ? for the same app. Why ? I manged to remove 2 of them using pm uninstall so as to keep just 1 - but I get the below error, after being stuck with 2 instances remaining instead of 1. pm uninstall com.google.android.trichromelibrary_484407333 -- Why 4 instances of the same app. Is it by design ? How do I know which app tried to install the additional instance of trichrome library and why did it do so when 1 exists
-- This happened in the past too. How do I ***prevent recurrence.*** So I dont have to clean up everytime.
-- Other than brute rm -rf on the un-wanted folder anyway I can uninstall the unwanted instance
