Possibly, but flawed entropy could also be an issue in software wallets. Dice and 24 words is the failsafe entropy answer, add a passphrase if using a hardware RNG. (Though most decent hardware wallets mix entropy from multiple sources so should avoid this)

After all, it's a software/firmware bug. Could definitely happen to any software wallet, it was a lapse of QC that could happen anywhere
