Hi Michael,

> In this particular case the -mempoolfullrbf configuration option is in the recent Bitcoin Core 24.0 release and so can be used both on mainnet and the default signet, testnet etc. What could be tested on this custom signet that can't be tested on the default signet with Bitcoin Core 24.0? Perhaps there are some things that are easier to test with a smaller custom signet network starting from scratch?

1. Signet miners and dictators are not interested to use full RBF
2. Testnet is weird and I only use it when a project doesn't support signet
3. Mainnet v24.0 is not released yet although Peter Todd is trying few things, I am not even sure if it will be available, testing should not depend on politics.
4. Main/Default Signet miners and dictators did not respond or agree to use full RBF.

Testing is important and I love it. I do not care about others.

> I know a number of people have struggled (e.g. [0], [1]) to get a custom signet set up. I think the CTV signet took a while to get set up too. It seems you followed the instructions on the Bitcoin wiki [2] for setting this one up? Was there anything you found difficult or was counterintuitive getting this custom signet set up? You are the sole block signer on this custom signet. How regularly are you mining blocks (e.g. strictly every 10 minutes, replicating the Poisson process on mainnet, adhoc etc?) Are you running this custom signet node on the same machine as a default signet, mainnet, testnet full node? I'm a little tentative to start joining custom signet networks on the same machine that is already running other nodes but perhaps there are no problems. 

I had no issues except this command:

``
$ ../contrib/signet/miner --cli="./bitcoin-cli" calibrate --grind-cmd="./bitcoin-util grind" --seconds=600
```

I had no clue we need to wait for some seconds/minutes for output. Although its okay.

I used default settings and it should mine with it forever or my AWS subscription is cancelled. 

I am trying to help Bitcoin. Although not a big influencer. If most of the developers think its okay to test it directly on mainnet, there is nothing wrong with it. You will get some insights/bugs from this experiment if enough users try it.
