yep absolutely. While you can use a seed siner every day if you're transacting with Bitcoin a bunch, seed siner is definitely more of a device that's focused on long-term cold storage. All of your seeds are backed up physically either on a piece of metal or however you choose to store your seed.
My current setup is I have a few cold storage seeds that I made with the seed signer (backed up on metal in a safe) and then I have some hot wallet seeds that I also made with the seed signer that are loaded into hot wallets like a samurai or sparrow.
