First off, this was my suggestion a while ago, and NO, that is not what would happen at all, because why would EVERYONE pick '-0.0001%'? Some people would pick  '-0.01%' or -0.02%', and I still don't think that the "wall" is a valid complaint. It means that here is a bunch of offers which NOBODY TOOK. That means someone else's offer was taken. It means that all those using the FRR are NOT competing because they don't have active swaps. I love how people keep saying "you aren't going to get good rates using FRR, you should actively manage or use a bot", and then say that they can't compete with the FRR. If the returns using the FRR are not great, and you can do substantially better by using a bot, then you simply have a situation where the more effort you put in, the better your returns are, which is awesome. Tons of people simply think that "something is better than nothing". I know we all miss the "good old days" when you could offer for much higher rates, but anytime something is very popular like that, the swarm of other people jumping in will always make the returns much lower. Compare the size of the swaps market then with its size now. It continues to grow, because in my opinion, it offers an extremely great risk to reward ratio.

Secondly, is there any way you could add your own FRR calculation to your bot? For example, could I either create or modify a bot that simply duplicates the current FRR calculation and offers at that rate? Again, I think it is interesting, because if everyone simply chose to use that calculation (as they ARE doing right now), the situation would be identical (besides the floating of the rate) and you would still get a "wall". I just think that the "wall" that people are complaining about will always exist in that there are a lot of people competing for a fixed amount of demand, the people willing to go the lowest are the ones who make ANY return, and right now, you have people who are using the FRR in order to passively gain returns staying OUT of that competition at least some of the time (whenever there is a wall). Lastly, if people think that people "undercutting" the FRR "wall" is lowering the rate, they are right, since that would factor into the calculation. Easy, simply enter it above the FRR, and once it gets eaten up, you will get even higher and it keeps rising. This doesn't happen because people are displaying their TRUE minimums and they are much higher than their STATED minimums. If no one wanted to offer a swap underneath the FRR, their would be no offers. So even though some people might complain, others seem to be jumping in front to push that rate lower...
