The chance of supported blocks and block types being eroded should be configurable.

Ideally Slow, Medium, Fast, and Full Custom.

Curseforge user Areolata provides an additional example of why this feature request is important:

I have been loving this mod but had to turn it off recently.
I decided to build a semi-automatic farm which I haven't done in my last two worlds. I discovered right away that the erosion mod destroyed it when built in the standard way. So I made the side channels into still water instead of the normal running water and I lowered the end channel by one block so it wasn't touching the dirt. However water coming out of the dispensers for a couple seconds still eats some of the dirt away. The erosion on dirt is way to quick.
My randomtickspeed is set to the standard 3.
What can I change to lengthen the time the dirt is degraded so I can still use this farm type?
FYI This is the build design I used for the farm: https://www.youtube.com/watch?v=gu18-3td7p0

See #13 as the better solution for this issue.

Published version Water Erosion 1.1.2 for Forge on 1.14.4 and 1.15.2. Adds water-erosion.toml configuration file to enable/disable Farmland erosion.

Lots more to do before I can close out this issue, but this is the single most requested feature.
