placeholder text should also be multiline please

a lot of my fields I couldn't use the placeholder text since it only displays it on 1 line which would confuse the form filler, so I have to use prefilled text which isn't ideal as it needs to be selected and deleted and I need to explicitly state that it's an example. for the new UI sidebar could it let us have "multi-line placeholder text" please? then I could delete the Example line. Also the default load size of multi line inputs should be large enough to display all text that is either "placeholder" OR "pre-filled" I think, would you agree? I don't care about that quite as much as just ability to have more multi-line fields including placeholder text field.
