FYI....do it or not......if you want those iCloud pictures download them to your hard drive.....the internet is going down shortly and never coming back....everything will be lost... entirely new internet is coming....it won’t be anything like the one we use now..
fYI I have 25,155 photos stored in my Apple I-Cloud drive, every single one of those photos is also stored locally as full size original files on an external SSD as a part of my photos library and that drive and library is also completely backed up to another 1TB external drive as a part of my Time Machine backup.
My photos and documents are important, as such I like to have both local backup and off site I-Cloud copies of everything.
originals + local backup copies + off site backup copies = security
