Is Multi-Cloud and DevSecOps skill mandatory for changing jobs?

First of all, we need to understand, what is multi-cloud and devsecops, before jumping to conclusion. So let't understand:

What is Multi-Cloud skill?
In simple words, multi cloud skill is, a person having knowledge or working experience in more than one public cloud. e.g. AWS and Oracle, AWS and Google Cloud or AWS, Oracle and Google Cloud.

What is DevSecOps skill?
In simple words, a person having knowledge or working experience in Development, Security and Operation, or one expert in one of that area.

Now come to main point: is Multi-Cloud and DevSecOps skill mandatory for changing jobs?
I will say YES, as if you want to get highest paid job in IT (other then managing), then you have to learn at list one or more than one cloud and good understanding of DevSecOps tools, like Ansible, Terraform, Jenkins, Nexus, Packer and many more.

This is my personal opinion and it may be differ with others opinion.
