Not even the bitcoin coders want to do that. The bitcoin core is almost dead at the moment, there are just tiny updates and everytime that something gets fixed, another issue start.
do you think there should be a reward for a person who volunteer computer internet and lot of disk space for bitcoin full node ?
I would do it, but it is not easy, just think about it, if the real coders haven't did it, then why would you do it? It means that it is extremely difficult, and expensive.
It doesn't justify that, but we all know that it is pretty impossible to try to fix something that is not ours. The same happens with all the other altcoins that are suffering huge issues with their nodes.
