...that punctures tire sealant won't fill can be plugged so you can continue riding tubeless?

And, more often than not, this is a long-term solution that will keep you from having to replace your tire until it's worn out.
There are a variety of different plug options on the market, including the 'bacon strip' style kit from Genuine Innovations and others, and from Dynaplug, which began making its system for car and motorcycle tires in the early 90s.
It's a good idea to learn how to use whichever style you choose (practice on a spent tire while it's still mounted on the rim), and carry it in your repair kit for a fast and easy fix-a-flat option. Plugs will not fill longer gashes, but there are different sizes of plugs/strips, which can also be folded or doubled up to fill fairly sizable holes.
