My company is using loopback3 for our backend and the effort to upgrade to loopback4 seems very high. I'm not sure I can justify the business value to my boss. What are the risks of continuing to use it after EOL in December 2020? I assume I can regularly check npm audit + keep an eye on snyk alerts and upgrade any dependencies which have security issues. (This might include forking loopback/loopback-component-storage etc.)
