That, somehow, seems like the wrong conclusion. Why not try to solve the problem of Excel taking longer than 30 seconds to export a RTF table?

Thankfully, that can't happen :). XLSX has a row limit of 1,048,576 rows.
In all seriousness, I don't have an answer for you other than that the developer that's looking to shove >1M excel rows around should find a better solution than the clipboard. I've done more than my fair share of work pushing excel spreadsheets around (and I've even worked on Excel add-ins). There are plenty of performant ways of accessing large volumes of Excel data, none of them involve the clipboard. Most of them even work on non-Windows platforms.
The arbitrary row & column limits in Excel (XLS was pretty small, XLSX is quite a bit bigger, but still arbitrary) are annoying and I cannot begin to tell you how many hours over the years I've wasted due to this limitation or Excel silently truncating large CSV files on import.
Excel is an intensely business-critical product and has a lot of smart folks working on it. There are tradeoffs you're eliding and I'm confident that they know of them.
