Accented characters at first place

In every single keyboard in the world, if you long press a letter, you get a variety of additional symbols and accented characters (according to language) at first position. The reason is obvious, you type more words than special symbols like brackets. In Czech language, almost every word has at least one accented character. With SwiftKey, where accented characters on second position after brackets etc, typing is even worse than with stock keyboard. I love many things of SwiftKey, but this is major issue while typing in language using diacritics.

This is example of text in Czech, it is about SwiftKey by the way:

SwiftKey je jedna z nejpoužívanějších virtuálních klávesnic ve smartphonech. Někteří výrobci, např. Huawei/Honor nebo Sony, ji dokonce do svých nadstaveb předinstalovávají jako primární klávesnici, ale stáhnout z marketu a instalovat na platformy Android a iOS ji může každý. Nově je androidová mutace SwiftKey zase o něco chytřejší. Microsoft jako její současný vlastník do ní přidal překladač v reálném čase.

You see how many diacritics is there? Can you imagine how insane it is to write this while every long tap option has a bracket or comma at first position?

I saw similar topics here with Hungarian user complaining and the topic was flagged "not planned". Why? This is not about improvement to be the best keyboard out there, this is more like issue to be fixed for SwifKey not to be the worst keyboard available.
