Official statement

With hreflang, each country URL must be indexed and ranked separately. If you create multiple country versions of the same page in a highly competitive market, it lessens the relative strength of your pages compared to competition that focuses everything on a single URL. This can be tested page by page before a broader rollout.

TL;DR

Using hreflang on multiple international versions of a page can reduce its strength. Each version needs to be indexed individually, which weakens your standing in a competitive environment. Test the pages first before generalizing.
