As long as Node understands to use the project-specific version of TypeScript (i.e., the one in node_modules or the PNP equivalent), that should be fine.
But it would be a step backward to need to globally upgrade TypeScript (as you do with npm), since some older projects will not be compatible with newer versions of TypeScript.

Ask me how I know. ;)
