In response to an earlier comment, I'll shed some light on how we decide which requests to work on and in what order. The Excel team considers many factors when deciding to invest resources in addressing requests, such as applying Conditional Formatting to Named Ranges. In addition to the number of votes, we consider the complexity and effort to implement (how many people do we need to work on it and for how long?), risk (for example - Does it have performance implications?), backward compatibility (will it cause a problem for people using old versions of Excel?), to name a few. Although Excel has a large team of engineers, we're not able to work on all the projects and features that we'd like to tackle, so we always need to make tough decisions about which things we can't fit into our near-term plan. For the specific case of Conditional Formatting being applied to Named Ranges, even though it seems like a straightforward idea, it is quite complex. Old versions of Excel will not support the new behavior, so there would need to be some hybrid approach that will be suitable for old and new versions. We need to make sure that it doesn't cause a problem if someone with Excel 2019/2016 opened a file with one of these rules. Also, named ranges can be dynamic, meaning that the range might change and conditional formatting rules would have to be adjusted when the workbook is calculated. The complexity of it makes it a lot more time-consuming to implement compared to many other features, which makes it difficult to prioritize over many other requests.
