rock-border cannot be presumed

OK, but having everything presumed or not brings another dimension to symbols - it can complicate things a lot. Adding one presumed symbol is OK, adding presumed versions of all symbols is not possible.

Having types and subtypes was an error in the therion concept in the beginning. Having only types and flags would be probably much better, but it is too late to change this.

Another example is visibility. We have visible flag for each symbol (on/off) but also we have wall -subtype invisible symbol. Both are doing the same :((

OK - changing therion this way would be easy - but converting existing data is difficult. I would be very happy if I could remove subtypes, but  it would be quite substantial change...
