This is one hyper annoying area.

It is possible to get around it, but it's ugly, drop to L1 and override logical id:

   let vpc = new ec2.Vpc(this, 'vpc', { natGateways: 1 })
   let cfnVpc = vpc.node.defaultChild as ec2.CfnVPC
   cfnVpc.overrideLogicalId('MainVpc')
You have to do this literally for every resource that's refactored.

For us, we run 2 stacks. One that basically cannot/should-not be deleted/refactored. VPC, RDS, critical S3 buckets - i.e. critical data.

The 2nd stack runs the software and all those resources can be destroyed, moved whatever w/o any data loss.

+1 CDK refactoring is annoying and ugly

in my experience you'd need to read the CDK source code to find the offending node and call `overrideLogicalId`

there is a library to do it in nicer way: https://github.com/mbonig/cdk-logical-id-mapper

however it does not work in every case

Why, dear god, you put VPC and RDS in one stack? They are much better off as separate CFN stacks.
