Linters attempt to look for "less than best practices". When you update a linter, you often also need to update code for the new style rules (unless you just don't care about the results). Those reports can be helpful, because those style rules can also warn about real problems like security vulnerabilities. But most are minor issues, so it may make sense to delay them.
I would generally prioritize outputs of tools that are designed to find serious problems (like security vulnerabilities), and then update things like linters when I can (but consider those lower priority). We should be unsurprised to find developers prioritizing some kinds of reports over others.
