I didn't think of it as a hard limit. Rather, it's an observation that
this UI design doesn't work well for more than a handful of rows.

A grid helps in that people are used to scrolling Excel sheets, but it
doesn't make it easier to grasp the whole sequence either.

But it would no longer be readable as text, then. That is, "0 until year
5" is in English and makes it easier to understand the control for a
first-time user. "0 year 5" is cryptic and requires being familiar with
the UI or reading the manual...

The question is how to convey this to the user. It's the kind of thing
that is hard to remember (for me, anyway), so some hint directly in the
UI would IMHO be in order.
