We have an internal prioritisation process that takes into account how popular the node is, how long it would take to fix, how many users are impacted and a couple of other things. Recently we have had some fairly urgent to fix which can result in other issues being moved down the list.
I take it the specific issue you are referring to is the Magento Store code issue which is still on my list to resolve but has a low priority score at the moment and may be the sort of thing I pop in between other issues.
Most of the time small issues are fixed fairly quickly, there are other options available though if you are handy with Typescript our code is available on GitHub and you can pop in a PR.
It ofcourse depends on your use and the costs of the workflows in other platforms. But for small issues it can often be worth it to hire a n8n partner for example to do the PR for you, if you do not have the expertise yourself.
